1. What are your bankroll requirements for your current level, and what amount are you working toward for your next step up? I started playing ($5NL) with 30BI's ($150). I also play multi-table and single-table SNG's from time to time, so my BR is in the $220-$250 range at the moment. But I need to log at least 15-20K hands at $5NL regarless of how much money I earn from other games. I will start easing myself into $10NL by playing 1 table while on 3 tables of $5NL, then gradually change $5 tables to $10 tables till I'm comfortably no longer playing $5NL. (I did this with $2NL to $5NL and the transition was smooth). Once my Bankroll gets around the $275 mark I'll begin easing into $10NL. During this time I won't let my BR dip below $250.

2. Do you have a stop-loss when you move up? If so, give us the move-up amount and stop-loss in BI's, please.
5BI's below my starting roll. So if I 'officially' (see above how I 'ease in as opposed to jump in') start $10NL with $300, and my bankroll dips to $250, I'll grind $5NL till I make back at least 2-3 of the 5 BI's lost before I continue. Once I'm beyond $300 though I will tolerate larger swings. I just want to avoid them if possible during the transition stage.

3. Robb says nitty bankroll requirements are better for long term earnings. IOPQ says reasonable (but not nitty) bankroll requirements speed up your earning by promoting you to higher level faster. With whom do you agree, and why?
I think it really depends on who you are and your poker experience. The first time I attempted online poker my BR MGT was poor, as a result I went broke. So now to ease myself up the ladder I prefer to have a fair cushion behind me. I don't want to donk my roll away, and I think the more buy-ins you have, the lesser the chance of this happening. If your extremely solid emotionally though with only have 20BI's or whatever then I'm sure that's fine. Just make sure you have very strict stop losses set out. A 5BI downswing kills 1/4 your roll. Since this is the beginners forum, I'd have to go with Robb's advice on being nittier for the above reasons. It's too easy to go on tilt if you're new to the game because (for me at least) pyschological mastery takes a bit of time. For the nitty requirement you need dicipline. But if you can put in the time to get hands in, it really isn't that long before you're moving up. 1 level a month is so doable. I think it's worth at least having some sort of plan rather than just depositing and playing whatever you feel like. This way you're actually thinking about how you will strategically build your roll. It makes things less of a gamble.

4. Spoony's suggested bankroll requirements for the micros (and a learning plan for poker) is quoted below. Discuss its pros and cons. What's good about a player who follows this? How long will it take?
Well I'm doing something similar. Although I just have 30 for $5NL, and 30 for $10NL, but I will probably increase it to 35-40 once I hit $25NL or $50NL. TBH it doens't take that long. Yes somedays it seems like forever, but it's really not. You can move up a level in a month or two if you put the time in. Within a year someone could easily get to $200NL and beyond (in fact didn't Stacks do this?). It will just take dicipline and hard work. So the Pros are: you will learn alot along the way. Your dicipline and worth ethic will improve because you really need to work to move up. It's not the same as just deposting a few hundred here and there and sitting at a 2/4 table. The other thing that's great about a player following this is they will realize the level that they no longer have an edge. You'll start losing at a higher stake eventually if you aren't updating your knowledge/skills. This method saves you money because you will realize the level you struggle with. You'd know right when things go wrong if you work all the way up from $5NL or $10NL. If you start right at $50NL or $100NL you may not have the game yet, and you won't know what level you can beat because you skipped everything in between.
Con's: I suppose if you have lots of money you'll just hate gambling with $2 and shit, but whatever, I think the pro's outweigh the con's here. There are definately some unique skills one will acquire by following the 'ladder' method as opposed to the 'hey letz jump into dis $5/$10 NL game dat sounds cheap rite?' method. I think BR MGT really comes down to what are you looking to get out of poker? If you're here to excel, (which I'm sure most FTR regs are) then obviously you want to have a BR MGT system in place. If your just playing poker for fun and to gamb00l, well that's your choice, and you can probably just fuck BR MGT since you won't be winning anyway.

Yikes that was a long post! I guess I've been pretty deep into planning the development of my BR lately. I think it's definately an overlooked skill in poker, because it isn't always easy to execute (I think this is especially true for a newbie). Once you get into the habit though it's just part of the routine.
